Description

Lifting tool and lifting equipment Technical Field The invention relates to the technical field of lifting equipment, in particular to a lifting tool and lifting equipment. Background The cylinder block is used as a core component of the marine diesel engine, and the manufacturing and assembling process of the cylinder block involves multiple lifting operations, including links such as machining, finishing treatment, complete machine installation and the like. However, the cylinder block is generally in a box-shaped structure, has the design characteristics of complex shape, huge mass (often reaching hundred tons) and no special lifting lug or lifting point, and therefore the lifting process faces significant technical challenges. At present, the industry lacks standardized lifting tools for the component, the existing lifting operation generally depends on the fact that a steel wire rope penetrates through a cylinder sleeve hole and a gram hole to carry out bearing lifting, the cylinder sleeve hole and the gram hole are used as precise matching surfaces, the surface roughness and form and position tolerance requirements are extremely high, the wall of a hole is easily scratched and worn due to direct penetration and friction of the steel wire rope, and accordingly follow-up assembly accuracy is affected, and even stress concentration is caused. Secondly, wire rope only wears to locate jar sleeve hole and gram hole, and the tiny swing in handling process probably leads to wire rope to remove for the cylinder block, and the stress point slides, and then has the potential safety hazard that handling stability is poor, easily produces impact load. Accordingly, a need exists for a handling tool and handling apparatus that addresses the foregoing issues. Disclosure of Invention The first object of the present invention is to provide a lifting tool, which solves the problems of the prior art that when a cylinder block is lifted, the wall of a cylinder sleeve hole and the wall of a gram hole are easily scratched to influence the subsequent assembly precision, the lifting stability is poor, and impact load is easily generated.
